It seems implausible that Arsene Wenger has never beaten a particular rival over so many encounters, even if that other manager is one as successful as Jose Mourinho.

Chelsea manager Jose Mourinho has hit back at Arsenal boss Arsene Wenger and defended his team's tactics ahead of their trip to Emirates Stadium on Sunday.
Mourinho and Wenger have been part of a long-running rivalry that has extended over the past 11 years, with sparring between the duo before, during and after matches, capturing headlines along the way.
